Miss the April 15 deadline & the penalty is $25,000. It reaches a US single-member LLC owned by a foreign person that had a reportable transaction during the year, even when the LLC earned nothing and owes no US tax. The disregarded-LLC mechanics run differently from the foreign-owned corporation version, which we cover in our Form 5472 guide for foreign-owned US corporations.
What Is Form 5472 for a Foreign-Owned Single-Member LLC?
Form 5472 is an information return that reports transactions between a US reporting entity and its foreign owner or other foreign related parties. For a single-member LLC with a foreign owner, the LLC itself is a disregarded entity for income tax purposes, but Treasury regulations pull it back into a reporting regime that treats it as if it were a domestic corporation for this one purpose.
Specifically, for tax years beginning after December 31, 2016 and ending on or after December 13, 2017, a foreign-owned domestic disregarded entity is treated as a domestic corporation solely for the reporting and record-keeping requirements of IRC 6038A, under Treas. Reg. 1.6038A-1(c)(1) and Treas. Reg. 301.7701-2(c)(2)(vi). Both date conditions have to be met, and the applicability rule sits in Treas. Reg. 301.7701-2(e)(9). Outside that reporting rule, the LLC keeps its disregarded status and its income is taxed the way a disregarded entity's income has always been taxed.
Who Has to File Form 5472 for a Disregarded Entity?
Any domestic single-member LLC that is wholly owned, directly or indirectly, by one foreign person and that had a reportable transaction during the tax year has to file.
Ownership by a foreign individual, a foreign corporation, a foreign trust, or a foreign partnership all count. Sole ownership can be direct or indirect, but indirect has a narrow meaning here. Under Treas. Reg. 301.7701-2(c)(2)(vi)(B)(1) it covers ownership held entirely through other disregarded entities or through grantor trusts, domestic or foreign. A chain that runs through a regarded corporation or partnership is not looked through, so the owner in that chain is the entity itself.
That distinction matters, because a real corporation sitting in the middle of the chain changes which reporting rules apply. Foreign ownership inside a corporate structure brings its own layer, covered in our Form 5471 filing guide.
This is a broader net than most owners expect, because it captures LLCs that never generated a dollar of US-source income. The IRS built the rule to get visibility into cross-border money flows through disregarded entities.
Why Does the LLC File a Pro Forma Form 1120?
The pro forma Form 1120 exists to carry Form 5472 to the IRS. The disregarded entity reports no income and no deductions on it, because a disregarded entity doesn't compute its own taxable income for US federal purposes.
The 1120 functions as a cover sheet. Completing it like a normal corporate return is the error we see most. The form is marked in a specific way, only certain identifying boxes are filled, and the package does not go where corporate returns go. Getting any of that wrong means the IRS treats the filing as never made, & the $25,000 clock keeps running.
What Counts as a Reportable Transaction?
A reportable transaction is any contribution the foreign owner makes to the LLC, any distribution the LLC makes back to the owner, and any amount paid or received in connection with the entity's formation, dissolution, acquisition or disposition. There is no minimum dollar amount, so one capital contribution to open a bank account triggers the filing.
The list itself comes from Treas. Reg. 1.6038A-2(b)(3), which paragraph (b)(3)(xi) expands for an entity treated as a corporation under Treas. Reg. 301.7701-2(c)(2)(vi). Plenty of small, quiet LLCs end up with a filing obligation they never saw coming.
Transactions That Trigger the Filing
Important- The foreign owner contributes to the LLC, and that includes a capital infusion to fund a bank account or cover startup costs.
- The LLC distributes money back to the owner.
- Money changes hands when the entity is formed, dissolved, acquired or sold.
The regulations also require the entity to keep records sufficient to establish the correctness of what it reports, and thin records are penalized on their own footing.
Do I Have to File if My LLC Had No Income or Activity?
Yes, if a reportable transaction happened during the year. Zero income changes nothing. The obligation applies even when the LLC has no US business activity at all, as long as one of the transactions above occurred.
Owners routinely skip this filing in the LLC's first year because there was nothing to report from an income standpoint, while missing that the funding contribution that opened the bank account was itself the reportable event.
A related trap sits on the tax year itself. The LLC uses the same tax year its owner uses for US tax filing purposes, and if the owner has no US filing requirement at all, the LLC's tax year is the calendar year.
How Do I Get an EIN for a Foreign-Owned Disregarded LLC?
You apply on Form SS-4 and name a responsible party. A foreign owner with no SSN or ITIN can still get the EIN for the LLC. The online application is closed to that applicant, because it requires the responsible party to hold a US taxpayer identification number, so the SS-4 goes in by fax or mail, and an applicant with no US place of business can also apply by phone.
Getting the EIN is a separate step from state LLC formation, and it has to happen before the Form 5472 package is filed, since the EIN is one of the identifying items on the pro forma 1120.
First-year filings stall on the responsible party field. Leaving that field blank, or defaulting to the registered agent, is one of the more common reasons a first-year Form 5472 filing gets delayed past the deadline.
When Is the Form 5472 Package Due?
The due date follows the Form 1120 due date, April 15 for a calendar-year entity, moving to October 15 if Form 7004 is filed by the original due date. Because the entity cannot e-file, the extension request goes in by mail or fax as well. For calendar-year 2026, that means April 15, 2027, or October 15, 2027 with a timely Form 7004.
This package cannot be e-filed. The Form 5472 instructions say so directly, which is a genuine difference from how most business tax filings work today, and it catches you off guard if you assume everything is electronic. Because the filing goes in on paper, building in time for delivery and confirming receipt matters more here than on an e-filed return, where an acceptance confirmation arrives automatically.

What Is the Penalty for Not Filing Form 5472?
$25,000 is the penalty for each taxable year and for each related party a Form 5472 was required for, under IRC 6038A(d) and Treas. Reg. 1.6038A-4(a)(1), so an entity with three foreign related parties can face three separate $25,000 penalties for a single year. Another $25,000 applies for each 30-day period, or fraction of one, that the failure continues more than 90 days after the IRS mails notice, with no stated maximum. Our Form 5472 guide for foreign-owned US corporations covers the penalty and reasonable cause in depth, and our guide to the delinquent international information return submission procedures covers the road back for an owner who has already missed a year.
Does Filing Form 5472 Create a US Income Tax Liability?
Filing Form 5472 creates no US income tax by itself, because the reporting duty is separate from any tax liability. The disregarded entity's income, if any, flows to the foreign owner, whose own US tax obligations depend on separate rules about US-source income and any US trade or business.
The package also doesn't cover anything else the LLC owes. A US LLC is a US person for FBAR, so a foreign bank account it controls over $10,000 puts FinCEN 114 on the calendar. A new foreign investment into a US business generally carries a Commerce Department Form BE-13, due 45 days after the investment, which is a different agency with its own penalties. State franchise and annual reports run on their own clock too.
Whether the foreign owner owes US tax is a separate question, answered by the US-source income and trade-or-business rules in our Form 1040-NR guide for nonresident aliens.
